May be, my question is simple, or, may be, not, but I'm new in OCC and I couldn't find something like this in examples.
In my program I build big topology (compound) from edges and polygons, every node in it has it's own identifier (number). And when user selects node, I need to know it's identifier for to load info about it. Can I keep this number somewhere in graphic objects and get it by OCC api, or I have to keep it outside and think, how to associate it with selected graphics myself? Or, may be, OCC has his own way to identify such elements and I can use it?
Thanks for any advices.
